This book enables readers to gain a deep understanding of the challenges related to the design of a charge pump (CP). Analysis, modeling, design strategies and topologies are treated in detail. Novel and high-performance CP topologies and related design are organized in a coherent manner, with particular care devoted to ultra-low power and energy harvesting applications. The authors provide basic theoretical foundations as needed, in order to set the stage for readers’ comprehension of analyses and results. Exhaustive methodologies are presented and analytical derivations are included, enabling readers to gain insight on the main dependencies among the relevant circuit parameters. Although the material is presented in a formal and theoretical manner, emphasis is on the design perspective, using many practical examples and measured results.

Charge pumps are finding increased attention and diversified usage in the new era of nanometer-generation chips used in different systems. This book explains the different architectures and requirements for an efficient charge pump design and explains each step in detail. It's filled with extra hands-on design information, potential pitfalls to avoid, and practical ideas harnessed from the authors' extensive experience designing charge pumps.

Due to the continuous power supply reduction, Charge Pumps, also referred to as DC-DC converters, circuits are widely used in integrated circuits (ICs) to generate high voltages for many applications, such as EEP-ROMs, Flash memories for programming and erasing of the floating gate, switched capacitor circuits, operational amplifiers, voltage regulators, LCD drivers, piezoelectricactuators, etc. A charge pump is a kind of DC to DC converter that uses capacitors as energy storage elements to create either a higher or lower voltage power source. The development of the charge pumps is motivated by ever increasing the needs for the small form factor (i.e small size and low weight), high-conversion-efficiency and low costpower management system, which is the best candidate suitable to meet the needs of continuosly shrinking portable electronic devices like MP3 players, cellular phones, PDA's.

A Charge pump circuit provides a voltage that is higher than the voltage of the power supply or a voltage of reverse polarity. Increased voltage levels are obtained in a charge pump as a result of transferring charges to a capacitive load, and do not involve amplifiers or regular transformers. Charge pumps usually operate at a high- frequency level in order to increase their output power within a reasonable size of total capacitance used for charge transfer. This operating frequency may be adjusted by compensating for changes in the power requirements and saving the energy delivered to the charge pump. Among many approaches to the charge pump design, the switched-capacitor circuits such as Dickson charge pump are very popular, because they can be implemented on the same chip together with other components of an integrated system. An extensive research focused on the design and timing scheme of Dickson, Static, Dynamic charge pump had been accomplished. A better charge Pump is proposed which have a better gain and threshold than other charge pumps discussed.

This edition provides an important contemporary view of a wide range of analog/digital circuit blocks, the BSIM model, data converter architectures, and more. The authors develop design techniques for both long- and short-channel CMOS technologies and then compare the two.
